Nice haul.

I'm quite interested in the network configuration.

You mentioned telnet, which largely implies TCP/IP, which in combination 
with Token Ring means specific things.  Things which I question about 
how much of a "bridge" the device was as much as a gateway.

Or, if it's telnet like, but not actually telnet ~> TCP/IP, then it 
could be other things, but I think they are more problematic to "bridge" 
to Ethernet.
